SolarFlare says

“I have these cracks on the side of my pool and everytime I dump it over some dirty water gets in there and gets right back in my pool so I needed to close those spots. I would like to give some helpful advice for those who think this is defective. It isn’t like most caulk where you cut the tip and just stick it in and go at it. The first few pics are where you screw off the tip and puncture a plastic film covering it. If you don’t do that it won’t come out the tip and the pressure will most definitely make it come out the back end. Old caulk guns have a poker thing for that too but I used a nail. There is also a cutter on the old ones so no need to search for your good scissors. When not in use it is a good idea to stick a nail in the tip but leave enough sticking out so you can use some pliers to get it back out. Since I didn’t want to become another gorilla glue girl I used an ugly baby spoon I was going to throw away anyway. Also had a sheet of plastic to wipe things off on. Since it’s for my pool I have no problem waiting 24 hours to fully cure. It is hot outside so it may take less time. A tarp is also about to go on it so I don’t have to worry about freak rain getting to it. Overall it’s been really good and will order again. I did get a little on my fingers and it came off with some nail polish remover. But I also immediately ran in and did it before it had a chance to dry.”
